使用内部的每个DIV构建div ID数组

Question

I'm trying to get the ID of each DIV inside this HTML code

<section id="choices">    
    <div id="talla_choice_24" style="">
        ...
    </div>
    <div id="color_choice_25" style="">
        ...
    </div>
    <div id="sport_choice_26" style="">
        ...
    </div>

    <button type="button" class="create-variation" id="create-variation" style="">Crear variaciones</button>
    <section id="variations_holder" style="display: none"></section>
</section>

So I made this:

function getDivId(div) {
    var inputValues = [];
    $("#" + div + ' > div').each(function() {
        inputValues.push($(this).val());
    })
    return inputValues;
}

And I call here:

$('#choices').on("click", "#create-variation", function(e) {
    var parent_id = $(this).closest("section").attr("id");
    var element = getDivId(parent_id);

    iterateChoices("", element[0], element.slice(1), 0);
});

I need to build something like this:

var element = new Array($('#talla_choice_24 input:text'), $('#color_choice_25 input:text'), $('#sport_choice_26 input:text'));

But I get this error:

Uncaught TypeError: Object has no method 'each'

What is wrong?

UPDATE

This is the code for iterateChoices() function:

function iterateChoices(row, element, choices, counter) {
    if ($.isArray(choices) && choices.length > 0) {
        element.each(function(index, item) {
            if (counter == 0)
                row = '<input type="text" required="required" value="" name="pupc[]" /><input type="text" required="required" value="" name="pprice[]" /><input type="text" required="required" value="" name="pqty[]" />';

            iterateChoices(row + '<input value="' + item.value + '">', choices[0], choices.slice(1), counter + 1);
        });
    } else {
        html_temp = "";
        $.each(element, function(index, item) {
            html_temp += row + '<input value="' + item.value + '"><br>';
        });
        html += html_temp;
    }
}

I also made some changes at this code:

function getDivId(div) {
    var inputValues = [];
    $("#" + div + ' > div').each(function() {
        inputValues.push("#" + $(this).attr('id') + ' input:text');
    });

    return inputValues;
}

And now the error change to this:

Uncaught TypeError: Object #talla_choice_24 input:text has no method 'each'

UPDATE 2

I still continue change getDivId() function to build a array like this:

 var element = new Array($('#talla_choice_24 input:text'), $('#color_choice_25 input:text'), $('#number_choice_23 input:text'), $('#sport_choice_23 input:text'));

But can't get it since array values are constructed as strings, see below:

function getDivId(div) {
    var inputValues = [];
    $("#" + div + ' > div').each(function() {

        inputValues.push('$("#' + $(this).attr('id') + ' input:text")');
    });

    return inputValues;
}

I'm getting:

("$('#talla_choice_24 input:text')", "$('#color_choice_25 input:text')")

I think there is the problem

Answer 1

You are using the val method on a div element, which just returns an empty string. There is no each method on a string.

---

You don't need the id of each div to get the input elements inside them. This will get you the inputs in a single jQuery object:

var element = $(this).closest("section").find("> div input:text");

If you really need an array of separate jQuery objects, you can then do this:

element = element.map(function(){ return $(this); }).get();

Answer 2

var arr = [];
$("#create-variation").on('click', function(){
    $("#choices > div").each(function(a,b){
        arr.push($(this).text());
    });
});

Answer 3

After some headaches I realized how to fix the (my) error, here is the solution to all the problems:

function getDivId(div) {
    var inputValues = [];
    $("#" + div + ' > div').each(function() {
        inputValues.push($("#" + $(this).attr('id') + " input:text"));
    });

    return inputValues;
}
